Astronomer flies high to spy on star formation

Dr Stuart Ryder is venturing into the stratosphere on a NASA jet to study the birthplace of massive stars.

Macquarie University astronomer Dr Stuart Ryder is in New Zealand to hitch a ride on a NASA jet and take a closer look at how stars are born in one of the most active stellar nurseries ever seen.

“We’re looking at a molecular cloud called BYF73, which is collapsing in on itself at extremely high speeds and forming massive stars,” says Stuart, who is an Adjunct Fellow with the Department of Physics and Astronomy at Macquarie University.

The world’s largest scientific instrument

In a whisper-quiet area of the outback in Western Australia, 133,000 radio telescope antennas are about to be built.

When complete, they’ll be able to pick up radio signals from the time when the first stars in the universe formed.

Japanese science changing Australia

The impact of Japanese technological prowess on Australian society is obvious for all to see. How we listened to music was transformed by audio recording technologies: from the Walkman to the CD. Home entertainment was changed by video tapes, DVDs, and game consoles. We rely on Japanese innovation in transport—reliable car engineering, the lean manufacturing techniques that made them affordable and, more recently, hybrid cars.

Fundamental science discoveries are bringing a new era of transformation. Japanese researchers were honoured last year with the Nobel Prize for their invention of the blue LED. They succeeded where for 30 years everyone else had failed. Incandescent light bulbs lit the 20th century; the 21st century will be lit by LED lamps—lasting a lifetime and using a fraction of the energy.

In 2006 Shinya Yamanaka discovered how intact mature cells in mice could be reprogrammed to become immature stem cells. By introducing only a few genes, he could reprogram mature cells to become pluripotent stem cells, that is, immature cells that are able to develop into all types of cells in the body. His work is transforming stem cell medicine and many Australian researchers are now using induced pluripotent stem cells to develop stem cell medicines.

2014 ATSE Clunies Ross Medals

John Nutt helped design and analyse the sails of the iconic Sydney Opera House early in a career that saw him pioneer the use of computers in engineering, and contribute to the first fire code for buildings.

Kevin Galvin’s invention of the Reflux Classifier has generated hundreds of millions of dollars in benefits to the Australian economy, and revolutionised mineral processing around the world. It maximises mineral recovery by improving the recovery of fine, but still valuable, particles. Continue reading Making plastics, mining, and engineering

Australian science changing Japan

It’s not a one way trade. Japanese lives are being improved by Australian inventions such as the bionic ear, gum that repairs tooth decay, sleep disorder treatments, lithium to treat bipolar disorder, aircraft black boxes, and anti-flu drugs, which are all in daily use in Japan.

And when you connect to a fast and reliable wi-fi network you can thank Australian astronomers who were searching for black holes and created tools for cleaning up radio waves.

Collaborating for the future

Today there are hundreds of thriving Australia–Japan research collaborations, many of which will have a profound impact on our lives in the years ahead.

Over the past five years, Japan has consistently placed within the 10 countries that have the highest number of collaborations with Australian researchers on Australian Research Council–funded projects. The ARC reports that the most popular disciplines for collaboration with Japan are: material engineering; biochemistry and cell biology; atomic, molecular, nuclear, particle and plasma physics; astronomical and space sciences and plant biology.

Seeing every cell in a whole adult brain
Scientists from RIKEN, the University of Tokyo, JAST, and the Queensland University of Technology have developed CUBIC—a technique for rapidly imaging the brain. They believe it will be scalable to whole bodies.

Biomedical applications for ‘magic crystals’
CSIRO and Osaka Prefecture University are developing biomedical applications for the massively absorbent metal–organic framework crystals developed by CSIRO.

How our phones track us
Billions of us now have phones that tell us and others where we are and what’s around us. A team from RMIT, Intel, Fudan University and Keio University is exploring the cross-cultural and intergenerational study of this phenomenon, and the implications for privacy, in three key sites: Tokyo, Shanghai and Melbourne.

Shared data reveals radio bursts, and a lunch break

In May 2014, a team led by PhD candidate Emily Petroff from Swinburne University was the first to see ‘fast radio bursts’ (FRBs) live, using the Parkes radio telescope in central New South Wales. The search was triggered by signals found in recycled data. They also discovered that someone was opening the kitchen microwave.

No more twinkle, junk and stars, now we know just where you are

Technology that ‘de-twinkles’ stars is being used to pinpoint manmade space junk and avoid devastating collisions like those dramatised in the movie Gravity.

Australian company Electro Optic Systems, based on Mount Stromlo in Canberra, is using adaptive optics and pulsing lasers to locate detritus too small for conventional radar. Ultimately, the company hopes to use similar lasers to remove the debris from orbit.

Adaptive optics helps the pulsing lasers to cut through the Earth’s atmospheric turbulence, which distorts and scatters light, by using a second orange-coloured laser to illuminate sodium atoms in the upper atmosphere.

Australia’s newest radio telescope

Fundamental questions about the Universe are set to be answered as a new radio telescope in outback Western Australia comes online, using multiple beam radio receiver technology to view the sky with unprecedented speed and sensitivity.

The Australian SKA Pathfinder (ASKAP), CSIRO’s newest telescope, uses innovative phased array feed receivers, also known as ‘radio cameras’, to capture images of radio-emitting galaxies in an area about the size of the Southern Cross—far more than can be seen with a traditional radio telescope.

Monster black holes supersize their galactic greed

Monster black holes lurking in the centres of galaxies are hungrier than previously thought, Melbourne scientists have discovered.

Astrophysicist Alister Graham and his team at Swinburne University have revealed that these so-called supermassive black holes consume a greater portion of their galaxy’s mass the bigger the galaxy gets. The discovery overturns the longstanding belief that these supermassive black holes are always a constant 0.2 per cent of the mass of all the other stars in their galaxy.
